Clock/Timing devices and systems are an integral part of many applications in the electronics and communications industry and the clock/timing devices and integrated circuits (ICs) used must not only be of the highest quality, but also provide advanced features that are reliable and highly accurate for their specific applications. The CDC857-2DGGG4 is a clock/timing IC that is designed to provide exceptional accuracy, stability and flexibility and is specifically designed for a wide variety of applications such as computers, telecommunications, consumer electronics and power management. This article will discuss the application fields and working principles of the CDC857-2DGGG4.

The CDC857-2DGGG4 is an advanced clock/timing IC that is designed to provide precise frequency synthesis and clock generation. It consists of a phase-locked loop (PLL) and a selectable divide-by-N counter. The PLL is used to generate a stable reference clock with a frequency that can be adjusted from a few kilohertz up to several tens of megahertz. The PLL circuit consists of a digital phase detector, a charge pump, a loop filter and a digital-controlled oscillator (DCO).

The PLL is connected to the selectable divide-by-N counter which is used to divide the output of the PLL by an integer number to produce a precise clock of a desired frequency. The counter can be programmed to divide the output frequency from 8 to 4096 times. The outputs of the counter are buffered by a low-gain amplifier and can be connected directly to TTL circuits. The output frequency of the counter is also adjustable and can be adjusted with an external reference clock.

The CDC857-2DGGG4 clock/timing IC is available in several package types and is ideal for applications such as telecommunications, industrial controls and computers. It is used for applications where accurate synchronization and frequency control over a wide range of operating frequencies are required. The CDC857-2DGGG4 can be used in frequency synthesizers, modulation systems, frequency dividers and other applications where reliable clock generation and time control is needed.

The CDC857-2DGGG4 is a highly integrated, highly accurate clock/timing device that is designed to provide stability and flexibility in a wide range of applications. The device is used in many applications that require precise frequency synthesis, accurate clock generation and time control over a wide operating frequency range. It is a reliable, accurate and cost-effective option that is designed to meet the requirements of many different applications.
